Generating 40 Rows Of 17 Random Numbers (1 To 5) That Will Sum To Specific Values
Feb 19, 2014
I need generating 40 rows (Columns of 17 (Columns A - Q) Random numbers (1 to 5) that will sum to specific values (60, 55..) in R Column, and to regenerate it on pressing any key.
The same has been done for one value in [URL] ..... but I need it for a set.
How to generate semi-random numbers? I have a small sample (26 points) that I would like to extrapolate out and plot on a skewed bell curve. The numbers represent a ratio which can never be less than one. The average of my sample is 1.0149 and the standard deviation is 0.01234. When I use the random number generator tool in the data analysis pack, it generates mostly good numbers, but it also produces numbers like 0.98 and such that are never possible in my data. I've made a plot with the random numbers, including the sub-one ones, and then just adjusted the x-axis so that they wouldn't show on the graph, but I know that that's not the correct way to do it. My graph isn't skewed as much as it should be.
1. I need to randomly generate either a 1, 6 or 12 every time I hit calculate (i.e. F9).
2. I want to specify the probablility of each result. For example, I want 12 to be the result 80% of the time, and 6 and 1 to be the result 10% of the time.
I need to generate 8 (random) numbers which should range between 0 to 80 and the sum of those generated 8 numbers should be 80.? How can I achieve this.
I'm looking to generate correlated random unifrom numbers between 0 and 1 using the excel random number generator, rand(), and a user defined correlation matrix - without the use of a plugin. I realise there are plenty of risk plugins I could use, but was looking for something excel/vba reliant so I could distribute it without the user having to install anything.
I've tried using a cholesky matrix, but most of time it resulted in one of the numbers being 1, and higher that all the others.
I would like to ask if there's a way to generate a random 4 characters in one cell and the specific random 4 characters that has been generated will be copied until the last cell of my preferred choice?
The format that I want is that:
yymmdd / random 4 characters that has been generated / 4 numbers that will increment sequentially
For example: in A1: 140330QWER0001 in A2: 140330QWER0002 in A3: 140330QWER0003 . . . . .
But here's the catch, the file that I am using when closed then opened again will generate another random 4 characters with the same format. If i opened this file tomorrow:
for example the date for tomorrow is March 31, 2014, the file will do:
in A1: 140331TYUI0001 in A2: 140331TYUI0002 in A3: 140331TYUI0003 . . . . .
I tried to record it, the Rand() function when copied will generate another 4 characters.
If you have a single column of random numbers, is there a way to give Excel a total amount you are looking for, and have it choose which numbers in that column total to that amount?
I have a spreadsheet of 1000+ companies and I want to take a random sampling of 100 of them. I would assume this could be accomplished by auto-filling a numerical value to each line of data (which I did), then scrambling only the column with the numbers (which I can't figure out), and then selecting the entire text and resorting it to put the numbers back in order and then just work with the first 100 rows (which I can do, if I knew how to make the numbers random).
Can anyone help, I'm trying to create some test data, eg 1000 rows in excel. In each cell a formula (?) returns some text such as Dog, Cat or Rabbit based on the probability Dog=0.5, Cat=0.3, Rabbit=0.2
I've come up with a messy solution of generating a random number between 1-100 and then using a lookup table where 1-50 = dog etc... it works but is long winded and difficult for other people to follow.
I've managed to write a random number generator that produces multiple sets with no repeating numbers per a set.
Now, to step it up a notch, I'm trying to create an even distribution of the numbers generated which is where I could use a hand. Here's my current code:
Code: Option Base 1 Sub RandomNumberStrings() Dim rndno As String, strg As String, msg1 As String Dim r1() As String, r2() As String
[Code]....
Equaling 500 numbers generated as intended, but my target is to get every number with an equal frequency.
Wondering if it is possible to generate a random 4 digit number based off an alphanumeric string?
Example;
Cell A1 has 123XVF1234 Cell A2 has 321AFW4321
In B1 I would like to have a 4-6 digit number that is generated based on the alphanumeric data in Cell A1 (and so on down the list). If that is possible, I would also need to be able to convert back the 4-6 digit number back to its original alphanumeric value
Example;
If B1 returns 643562 it would need to be able to be converted back to 123XVF1234
I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.
What I have In Column B, I have the datesIn Column I, I have engineers name What I need I want a macro to generate Serial Nos. (1,2,3....... n) in column A If an only if the date in column B is today's date and the engineer's name matches with the PC's username
Hi, I'm very new to writing Excel Macro's and wanted to know if I could do the following. Conceptually, I understand what I need done and think it should be fairly straightforward.
There's 2 main events in this loop (I hope that's the correct terminology):
Input 1) User defines the beginning cell to start the loop. In this case, A2.
Input 2) User defines the range of columns/rows to display. The formula for rows that I've thought of is 4r. So if a user wants 20 rows below cells A2, they simply input 5 for r. The number of columns is a constant 5. So if r=5, then I'd want the range to be A2:E22......
So we had a month long, company paid (woohoo!) "weight watchers" challenge. On 1 worksheet ("Stats"), I have the Name of every Employee (A Column), then their Start Weight (B Column), End Weight (C Column), Department (D Column) and finally Location (E Column).
I know how sensative some people can be about their weight, so I locked the page and created another worksheet named "UI", which will display the "Average End Weight" for each department. So Human Resources would be the department in cell A2 on the UI sheet, with City 1 being the Column Header in cell B1. There are 8 cities (offices) and 23 departments.
So, for cell B2, I want to scan through the "Stats" worksheet and locate all of the cells in the department and location columns that read "Human Resources" and "City 1" respectively. Then grab the "End Weight" for every row that meets these 2 criteria, add them up, and divide by the number of "End Weights" that were grabbed.
My solution would be to make a separate column for each department (and then each city, so essentially 8 columns to represent all the cities for each department), use a nested (maybe 4) IF statements to then list only the end weight if that particular row meets the criteria, then at the bottom of each separate column, add all the shown numbers up and divide, then draw the information from THAT number into the "Average" cell on the UI worksheet. But it isn't very dynamic and if i want to use this sheet next year, there will be more employee info to be added and it would be a mess..further more, it would be...what...23 Departments x 8 Cities x 155 employees = ~28,500 added cells.
Is there a way to generate a normal curve from just the statistical values (mean, std dev, etc)? I used the NORMDIST function but have to manually do the x values and it generates what I would descirbe as a "sample" curve. I would like to make one based on user input.
Column A lists an account code on the summary line of each invoice. I'd like to copy this account code upwards for each individual line of the invoice so that I can summarise each type of charge by account code in a pivot table.
I'm a bit stumped as to how to do it. If possible I don't want to have to modify the data itself in any way so that I can paste new data in the each day without altering it.
I've started on the right with a CountA function for each row, which I was intending as a means to identifying the blanks rows and discount them, but it also showed up that each line requiring an account code to be copied returns a 4 and each invoice summary line returns a 9. I'm just not sure how to reflect this in a function.
I'm attempting to write a macro that will select all the rows which contain a value in a specific column. Say for example, all the instances of "test" in column C, I need to select the entire row with that value in the column.
I should also mention that by using an autofilter, only specific row numbers are selected. The source spreadsheet is dynamic and will not always display the same value in the same row, and thus I need something a little more adaptable.
I have workbook "Sheet1" that has many rows and columns with values. Could I have code to find the cells value "plant2300" in column A and copy all the rows in column A that has the cell value "2300" into workbook Sheet2 (also copy with headers from Sheet1 to Sheet2 row 1).
I’ve got a spreadsheet with approximately 30,000 rows and I would like to create a macro which hides every row which has not the value 12, 14 or 19 in column I. What is the best way to do it? With an if statement?
I have a spreadsheet with columns and columns of data. What I'd like to do is identify which rows have blank/no data in all specified columns (H, K, O, S, U, W, and Y).
To clarify, I need to identify each row where all of these columns are blank (as opposed to each row where at least 1 column is blank).
Say I have two worksheets, "Sheet1" and "Sheet2". Let's also say A1 in Sheet1 could have one of four values: cat, dog, rabbit, mouse. Now, based on which value cell A1 on Sheet1 is, I need different rows hidden in Sheet 2. For argument sake let's say if cat is chosen rows 1-5 are hidden, if dog, 6-10 and so on.
